this has nothing to do with the question,

oh ok

darkknight · Answer

the formula for an angle formed outside a circle by intersection is
the angle equals $$1/2(difference ~of~ intercepted ~arcs)$$
basically angle equals 1/2 * difference of both arcs
You know one is 247, the other is 360-247 or 113
so your answer is $$1/2(247-113)$$

darkknight · Answer

think logically as well, you know that angle is acute, how can it be 160 degrees lol, that would be like this |dw:1620690456301:dw|
